I love the harmonies on this one. I really like it when music for kids is good on it's own regardless of the audience and doesn't assume that children can't handle any musical complexity. Most kids are quite the opposite, I would say. Our kids love this one and so do we, and not just when they're in the car.

I didn't find this earlier in the posts, but my apologies if I missed it. The penguin song is available at the iTunes Music Store (at least the US store) on a kid's compilation album called "Roll Play." The official title of the song is "Horatio the Penguin."
